PC/ABS demolding draft
Problem Phenomenon
Demolding drag marks.
Cause Analysis
Insufficient draft, large clinging force.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Increase draft; ②polish cavity; ③balance ejection; ④reduce clinging.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record the parameter changes, to facilitate locating the effective measures
Key Takeaway
Draft and polishing are the demolding guarantee.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later
